PM103x Optical Power Meter Interfaces Chapter 4 Operating Instructions

4.2.2.1 PM103

PM103 Special Features

The PM103 version of PM103x features a number of additional options, due to the DA-15 output

connector.

The PM103 is per default configured to RS232 configuration (+/- 5 V voltage level). This can be changed

to a UART configuration (0/5 V voltage level) such that the PM103 can be accessed by external micro-

controllers for instrument control and data export. The PM103 can also be adjusted to accommodate

micro-controllers using 3.3 V.

1. DA-15 Interface

2. Two Digital I/O ports

3. NTC input

4. Two Analog Output Ports

5. Real Analog Output

6. Autonomous Operation to Analog Output

7. Optional Use of 5 V - 36 V Power Supply

8. RS232 Operation

9. Adjustable Baud Rate via USB or Serial Communication (SCPI commands); The default BAUD

Rate is 115200 Bit/s.

10. UART Operation (i.e. for Control via an External Micro-Controller)

11. Instrument Control using SCPI commands (Serial Communication)

12. Power Meter Control and Output via USB
